I am a bit unsure how to take things from here. I need space to properly detach but am already missing W! I was going to go dim for a few weeks for my own benefit, but am not too sure now.
The fact that you're missing W doesn't mean you shouldn't detach and go dim--for your own benefit and to give your W the best chance of missing you and family life.
I think you did great both when she left and in your response to her question about S. I'm really impressed too at what you managed to do with your S. We just managed swimming with our S.
Your best bet, as I see it, is to keep doing what you were doing and to stick to your original plan for now. When is your W going to spend time with your S? There will be hand-overs so presumably she will have a chance to notice your DBing efforts even as you're dim.
